| 7475791 | Toroidal tank An improved underground water storage tank having a joined-doughnut (multiple-torus) configuration, preferably a double torus although single, triple, quadruple and other toroidal configurations are possible. The concept entails a lateral merger of two or more toroi... | 01/13/2009 |
| 6659303 | Tank for storing gas at high pressure The tank for storing gas at high pressure, such as a tank for a vehicle running on gas, comprises a confinement volume accessible via coupling means and defined by a duct disposed in a spiral coil so that the substantially rectilinear main portions of the... | 12/09/2003 |
| 6176386 | Pressure-resistant vessel A wheel-shaped pressure-resistant vessel for storing gaseous, liquid or liquefied fuel and which has a substantially rigid shape. Specifically, the vessel contains a substantially continuous shell of a fiber-reinforced resin. The shell has a central openi... | 01/23/2001 |
| 5111856 | Tank having a shell capillary effect A liquid and gas tank is provided for operation, in particular, in satellites subject to low acceleration, that utilizes a separation force produced by surface tension to collect liquid in a privileged zone of the tank without allowing gas to escape via t... | 05/12/1992 |
| 4878593 | Pack for flowable material A pack for flowable material, includes a tube (1) having at least one longitudinal seam, with a base and a lid (2) mounted at its ends. The lid (2) is made of thermoplastics material without any base material, is welded to the tube (1) and has a pouring d... | 11/07/1989 |
| 4817855 | Pressure vessel A toroidal pressure vessel storing pressurized gas defines an outwardly exposed axially extending structural part of an automotive vehicle. Heat transfer from outside the vehicle directly to the pressure vessel advantageously offsets gas-expansion refrige... | 04/04/1989 |
| 4790472 | Methods for manufacturing a toroidal pressure vessel A toroidal pressure vessel comprises two annular, complementarily formed axial sections which are intersecured along a duality of annular joint lines that circumscribe and are mutually offset along the axis of the toroid. The axial sections are formed by ... | 12/13/1988 |
| 4768688 | Suntan lotion bracelet A suntan lotion bracelet formed from a tubular body configured in the shape of a ring. The interior of the tubular body forms a chamber for receiving a liquid suntan lotion or other liquids or lotions to be applied to the human body, particularly, lotions... | 09/06/1988 |
| 4615452 | Compound toroidal tanks A tank for containing fluids, comprising at least two connected concentric toroid cells sharing a common axis, is provided. Each of the toroid cells encloses a hollow interior for holding the fluids. One or more surfaces separate adjacent toroid cells. Ea... | 10/07/1986 |
| 4582211 | Pressurized container of compound material A pressurized container of compound material, such as fiber compound matel for holding a pressurized fluid in said container has a torus shaped body with a fluid tight inner container member and an outer supporting winding shell for relieving the inner c... | 04/15/1986 |
| 4561476 | Toroidal pressure vessel A toroidal pressure vessel comprises two annular, complementarily formed axial sections which are intersecured along a duality of annular joint lines that circumscribe and are mutually offset along the axis of the toroid. The axial sections are formed by ... | 12/31/1985 |
| 4475662 | Toroidal pressure vessel of compound material A pressure vessel has an inner core which is gastight or liquid tight. The core has an inner toroidal shape and an outer cylindrical contour. A first plurality of filament windings is wrapped in a meridian direction around the core to establish constant t... | 10/09/1984 |
| 4318491 | Toroidal pressure vessel A toroidal shaped container including a body made from tubing and formed into a ring is disclosed.
